Chris LuandGitHub fe0a357624 exclusive_locks: clear renew-running flag before dropping isLocked (#10413 )

On renewal failure the renew goroutine stored isLocked=false before its
deferred renewGoroutineRunning.Store(false) ran. A concurrent RequestLock
interleaving there reacquires the lease (sees isLocked=false), sets
isLocked=true, then its CompareAndSwap on renewGoroutineRunning fails because
the old goroutine's flag is still set — so no replacement renewer starts. The
lock is then held locally with nothing renewing it, and silently expires on
the master after the lease TTL, admitting a second holder.

Clear renewGoroutineRunning before isLocked on the failure path so the
reacquire path always starts a fresh renewer. Builds and vets clean; no
behavior change on the success path.
